In this paper, we investigate the feasibility of using a fluoroalkyl-substituted fullerene/perovskite heterojunction (f-FPHJ) to realize efficient and ambient stable perovskite solar cells (PVSCs). The hybrid fluoroalkyl-substituted fullerene, DF-C60, is proven to effectively passivate the defects a...
